They learned about Bast, a cat goddess from the "City in a Mirage" around the Deadlands. Sas recognized the coin and gave some insight from a vision she had. -- this knowledge is still not known by the other two in the party. The ladies never shared this. The book "Legends from the Mist" told stories of different adventurers and lost lands, including on about Al'Quar. An adventurer spoke of a mirage city with pyramids, ziggurats, obelisks, Bast, etc.. He got stuck there for a long time but then he got out and around to see it was gone.
I really do try to make most of this original, but since Forgotten Realms is an integral part of the world I can't help if anything is used without formal permission, but is still "fair use" as I am just using this for my private games.
